LANCASTER -- One-hundred pound flathead catfish could eventually take over the Susquehanna River and disrupt its ecosystem, according to the Pennsylvania Fish and Boat Commission.

Last week, commission officials confirmed that the species recently entered the Susquehanna River. And officials are worried the predatory fish, which can reach more than 100 pounds, could cause problems for other species.

The agency is now looking for the help of anglers to help control the growth of the species, which is not native to the river.
